ROTARY GAS-ENGINE.

Specification of Letters Patent.

Patented June 9, 1908.

Application filed October 22, 1906. Serial No. 340,117.

To all whom it may concern:

Be it known that I, FREDERICK H. ARNS- BURGER, a citizen of the United States, residing at Stockton, in the county of San Joaquin, State of California, have invented certain new and useful Improvements in Rotary Gas-Engines; and I do declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings and the characters of reference marked thereon, which form a part of this specification.

This invention relates to gas engines and particularly to that type known as rotary engmes.

My object is to produce a rotary gas engine which will have a greater power than the type of engines now in use, also one which will be simple in construction; one which will be safe from explosion and one which may be regulated in all its parts with precision and accuracy without being complicated with any great amount of intricate mechanisms. This object I accomplish by providing a driving wheel suitably arranged within a drum or case; an explosion and compression chamber arranged above said drum; means for conveying the explosive from said explosive chamber to said driving wheel; and by such other and further construction as will appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views.

Figure 1 is a side elevation of the device, certain parts being in section. Fig. 2 is a vertical section of the same. Fig. 3 is a fragmentary view showing adjustable plates.

1 designates a base upheld by which is a circular drum or casing 2 in which is journaled a driving shaft 3 on which is secured a driving wheel 4, said wheel being formed in its outer rim with one or more buckets or cups 5, the wheel 4 for a short distance outward from said buckets or cups being formed with shoulders 7 bearing close to the inner side of the drum 2, the space between said shoulders bearing a short distance away from said drum, thus permitting expansion when heated without permitting the same to stick.

Arranged above the drum 2 is a compression chamber 8 and an ex losion chamber 9, the same being connected y means of a port 10, the passage of mixture from said comression chamber to said explosion chamber eing regulated by spring check valves 11 and 12.

Arranged in the chamber 8 is a piston 13 provided with a rod 14 pivotally connected to a link 15 connected to an eccentric 15 on the shaft 3.

16 is an intake pipe leading into the chamber 8 above the piston and 17 is a pipe leading from said chamber 8 below said piston to said intake pipe 16, said intake pipe being provided with suitable check valves. 19 is a lubricator connecting with said chamber 8.

From the explosion chamber 9 a port 20 leads to the drum 2 and 21 is a check valve in said port 20, said valve being rovided with a rod 22 extending through t e top of the chamber 9 and being threaded and provided with a thumb nut 23 and a spring 23 bearing between the top of said chamber 9 and said thumb nut 23.

In the drum 2 on both sides of the port 20 are adjustable plates 24, the position of the same being regulated by means of set screws 25 for the purpose as will appear. Just below the lower one of said plates 24 is the exhaust port 26.

27 is the usual spark being in the explosion chamber 8.

28 is a water jacket for the purpose of keeping the engine cool.

In practice the eccentric 15 and link 15 operates the piston 13in the chamber 8. The downward drive of said piston draws through the port 16 the mixture and the upward drive of said piston compresses the same and forces it through the valve 11, the port 10 and the valve 12, into the chamber 9. The spark from the plug 27 then explodes this mixture and it passes through the valve 21 and through the port 20 into one of the cups 5, thus driving the wheel 4 around, and then passes out of the port 26.

In order to keep the products of the explosion confined in the cups 5 until it exhausts, the plates 24 are adjusted by the set screws 25 so that the shoulders 7 will pass the same very snugly and thus act as packing rings.

To regulate the force of the explosions and to thus regulate the speed of the engine the tension of the spring 23 may be regulated by means of the thumb nut 23, and thus the o eration of the valve 21 is regulated for t e pur ose as above.

T e lubricant from the lubricator 19 passes through the pi e 17 into the chamber 8 above the piston an thence through the several valves to all arts of the engine.

The main feature of this, my improved en? gine, is the feature of the wheel 4 with the cups 5 in the outer rim thereof. This gives an immense leverage when the explosion strikes said cups, and greatly facilitates the rotary motion of the said wheel, doing away with all need of balance wheels or cranks.

Another valuable feature of this engine is the impossibility of an explosion of the engine. For instance, if any flame should by chance reach the compression chamber 8 and explode the mixture therein, the said explosion would merely pass back through the valves 12 and 11 into the chamber 9 and thence through the valve 21 to the cups 5.

Other features of the invention are its simplicity and compactness; its simple means of regulation of different parts; and its means for lubricating from one lubricator.

Another advantage of this engine is that the same may be either constructed as a two or four cycle engine by means of gearing on the eccentric connection 15.

This specification sets forth the main features of construction of this my present and preferred embodiment of the engine. Many small deviations from such detail may be resorted to however without departing from the spirit of this inypntion.

Having thus'desc bed my invention, what I claim as new and useful, and desire to secure by Letters Patent is In a rotary explosive engine, a drum, an inlet port, and an outlet ort for said drum, a drive shaft journaled tfierein, a drive Wheel mounted on said shaft within the drum and provided with pcri heral pockets, shoulders on the periphery o the drlve wheel adjacent each pocket, a compression chamber mounted on the drum, a piston therein, connections between said piston and the drive shaft, an explosion chamber in communication with the drum and with the compression chamber, check valves controlling the admission of explosive fluid from the compression chamber to the ex losion chamber, a check valve controlling t e admission of the fluid from the explosion chamber to the drum, and adjust ab e packing plates carried on the inner wall of the drum above and below the inlet port thereof, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

FREDERICK H. ARNSBURGER.
